How it works

Welcome to our tutorial on the Driven Data's Water Pumps challenge. Here you will learn how to get started with the
competition using R. In case you're new to R, it's recommended that you first take our free Introduction to R Tutorial. Furthermore, while not required, familiarity with machine learning techniques is a plus so you can get the maximum out of this tutorial.

In the editor on the right, you should type R code to solve the exercises. When you hit the 'Submit Answer' button, every line of code is interpreted and executed by R and you get a message whether or not your code was correct. The output of your R code is shown in the console in the lower right corner. R makes use of the # sign to add comments; these lines are not run as R code, so they will not influence your result.

You can also execute R commands straight in the console. This is a good way to experiment with R code, as your submission is not checked for correctness.

In the editor on the right, there is already some sample code. Can you see which lines are actual R code and which are comments?

Add a line of code that calculates the sum of 8 and 15, and hit the 'Submit Answer' button.
